title: [Variants of the anatomical structure of frontal sinuses based on the results of X-ray computed tomography].
abstract: The objective of the present work was to analyse computed tomograms of brain and paranasal sinuses obtained from 3,054 patients with a view to elucidating specific features of the latter's structure. The following structural variants were distinguished: agenesia, hypogenesia, and hypergenesia. Orbital, zygomatic, temporal, cock's comb, ethmoidal, and nasal recesses in the frontal sinuses were described. It is concluded that the marked structural variability of frontal sinuses is responsible for the great variety of clinical manifestations of frontitis.
